MJUSTABLE FLEXIBLE SHAFT COUPLmG Application filed @ctober 7, 1921. Serial 593,085.

To all whom it may concern:

Be it lnuown that l, Enwanu Morten, a citizen of the United States, residing at Newark, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Adjustable Flexible Shaft Couplings, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

This invention relates to couplings for shafts which permits one shaft to drive a other even though slightly disaligned and which also permits one shaft to be rotation ally angularly adjustable with respect to the other.

The objects of this invention are to provide a simple inexpensive coupling of this a character and one which permits convenient adjustment of the shaft alter the coupling members have been secured to their respective driving and driven shafts.

My invention is disclosed in the follow ing specification and drawings in which- Figure l discloses a side view of my cou= pling applied to the driving and the driven shafts.

Figure 2 is a front view thereof, one oi the clamps and its nut being removed, aloclring plate being shown out of engagement with the hub.

Figure 3 is a perspective view of one oi my retaining clamps.

Figure 4: 1s a sectional view through my cou ling.

igure 5 is .a per active view of a strengthening coupling ange.

Fi re 6 is a perspective view of the adjusta ls hub, and

Figure T is a perspective view of one oi nay locking plates.

New referring to the drawings more in detail and in which like reference characters in the several figures refer to like parts, 1 indicates a driving shaft, and 2 the driven shaft, which may for example be the rotor shaft of a magneto 3. Secured to the rotor shaft as by means of a nut at is a spider 55 having arms 6, only one of which is shown, each am being tapped to receive a bolt "Z passing through a flexible disc 8 which may be made of any suitable material such as vulcanized fabric or leather. This disc has a circular opening in which fits the hub 9 of a coupling flange 10. The flange 10 has two perforated cars 11 and bolts 12 pass through the disc and the perforations in the ears to bind the same together suitable cup-she d washers 25 being used as will bereadi y understood. Fitting snugly within the hub of the coupling flange 10 is the adjustable hub 13. This hub hasa toothed annular ring 14: engageable with slidable lochng (plates 15 each provided with an elongate opening 16 embracing the bolts 12 so that the plates may be moved radially away from the center of the coupling. The plates have teeth 17 adapted to engage with the teeth on the ring 14. to prevent rotational movement of the hub in the coupling flange. The hub is further provided with a keyway T8 for securin the same against rotation on the drive sha o outwardly from the center or by removin thorn, the coupling flange may be rotated with respect to the hub to adjust the angular relationship between the drive and the driven shafts. To secure the plates against accidental displacement and to prevent the hub from bein withdrawn laterally from the couplin ange, retaining clamps 19 are provided Each clamp is provided with an opening 20 to lit the bolt 12 and a lip 21 flared slightly away from the body of the clanip so that when the clamp is applied over the bolt and drawn down as by the cas tellated nut 22, the flared lip will embrace the edges of the plate 15 and force the same inwardly toward the center of the hub to cause the teeth of the plate to interlock iirnily with the teeth on said hub. The

clamp in itself is so shaped that the free ends of the lip fdrm teeth 23 to on go with the hub teeth to hold the hub against rotation in the coupling flange. The upper sur- "face of the clamp is extended so as to form an annular rim 2% sufficient to embrace the ring of the hub, thereby preventing withe drawal of the same from the coupling flange. it is to be understood that the clamp in itself with its two teeth is sometimes sunlcient to retain the hub against rotational movement, but with the provision of my locking plate I minimize the chances of the hub slipping around in the coupling flan e.

The above construction provides-a rea y Upon shifting the plates too means for rotating the magneto shaft with respect to the drive for properly tirn- I ing the magneto with respect to the engine,

the construction. of the various parts being verv simple.

aving thus described my invention What I claim is:

1. An adjustable coupling comprising a disc, a driven shaft coupling member secured thereto, a driving hub rotatably ad ustable with respect to said disc, teeth on said hub, clamping members having a peripherall disposed lip terminating in a pair of teet at itsiree ends for engaging said teeth on the hub at points a considerable distance apart, and means passing through said disc and clamping members for securrng the parts together in co-operative relatlonslnp. 2.
